摘要(Abstract)：

有功-相角下垂控制避免了将频率作为下垂量所引起的频率偏差问题,但同时导致了系统有功功率在分布式电源(distributed generations,DGs)之间难以精确分配。基于有功相角下垂控制,提出了一种基于微型同步相量测量的有功补偿控制方法。该控制方法根据量测的公共母线上电压相角信息,调节各个DG的相角参考值趋于一致,最终可以使所有DG的有功出力根据其下垂系数精确分配。为提升配电网孤岛系统的动态性能,对系统进行了小信号动态建模以对系统进行动态性能分析。此外,基于小信号模型,建立了补偿控制参数优化模型,可求解出使系统动态性能最优的控制参数。最后通过基于PSCAD/EMTDC平台的时域仿真结果验证了所提方法的有效性。
